The Samsung 840 Evo series comes with 120 GB, 250 GB, 500 GB and also 750 GB storage capacities as well with 3 years warranty period. Its obvious that Samsung’s plan is to make sure ‘everyone’ can buy an SSD depending on the capacity they can afford, however I am simply speculating on that since there is no official announcement about the price.

It is also being said that Evo would be using a feature called ‘TurboWrite’, but not much info has been put out… yet, but it is being said that it will increase write speed for lower capacity EVO models. As for 1 TB, I would be having a 1 GB LPDDR2 DRAM as a cache.

As expected, Samsung 840 Evo comes with their own Multi-core MEX controller with ARM’s core, advertised up to 520 MB/s Sequential Write and up to 540 MB/s reads with random writes and reads of around 66K IOPS and 97K IOPS.

Samsung XS1715 Enterprise storage SSD would be using non volatile memory of up to 1.6 TB storage capacity, which will be using PCIe 3.0 to provide max sequential performance of 3 GB/s and 76K IOPS.
